MOVEMENT CURE APPARATUS.

SPEOIFECATION forming part of Letters Patent No. 309,036, dated December 9, 188%.

Application filed October 14, 1884. (No model.)

To ctZZ whom it may concern:

Be it known that I, Mosns G. Flinrrnn, a citizen of the United States, residing in New York, in the county and State of New York, have invented certain new and useful Improvements in Electric-Motor Attachments and Apparatus for lliovement-Oure, of which the following is a specification.

My invention relates to apparatus designed to be employed in connection with an electric motor for actuating machines adapted to impart to the human body movements designed to aid in the recovery of health.

The object of the invention is to equip an electric motor with suitable means for operating a foot and leg exercising device, and also actuating a convenient form of rubber, and to render the rate of movement of the machines readily adjustable. Any suitable form of rotary motor maybe employed, and the shaft of this motor is provided with a crank-ar1n and pitman, through which an oscillating movement is communicated to a second shaft. At the end of this second or oscillating shaft there is placed a suitable shoe or holder for receiving the foot of the patient, and to this shoe there is given an oscillating movement when the machine is actuated. XVith the central shaft of the motor there may be coupled a flexible shaft, which in turn may be employed for actuating any convenient form of rubbingniachine. Applied to the motor itself there is a brake, the pressure of which is rendered adjustable by means of a suitable weight and lever.

In the accompanying drawings, Figure 1 is a plan view of amotor equipped with the several devices referred to, and Fig. 2 is an end elevation of the motor, and Fig. 3 is a plan of the shoe.

Referring to the drawings, A represents the motor, which is preferably constructed with a series, say siX in number, of armature-coils, a, surrounding corresponding cores,b. The cores 1) are supported at their respective ends in disks B and B and they revolve between corresponding confronting cores,c, which are surrounded by coils d. The circuit and commutator connections of the motor are of any wellmore fully described. The disks B are carried upon a central shaft, E, which. is revolved when an electric circuit is completed through the coils of the motor in a manner well understood.

At one end of the shaft E there is mounted a wheel, e, carrying a stud, e. A link or pitman, f, connects the stud c with an arm, f, which in turn is connected with a shaft, F, extending parallel to the shaft F. The revolution of the wheel E causes the pitman fto be alternately moved forward and backward, and in this manner an oscillating movement is given to the arm f, and thus to the shaft F. The arm f is provided with two or more holes, f, at different distances from its point of attachment to the shaft F, for the purpose of adjusting the point of attachment of the pitman, and thereby modifying the distance through which the shaft F is turned when it is being oscillated.

Upon one end of the shaft there is placed a shoe, H, adapted to receive the foot of the patient. The shoe is preferably constructed of a single piece of sheet metahwhich is struck out into approximately the form shown in Fi g. 3. It will be seen that this pattern consists of a central portion, h", having two lateral extensions, h and 7L3, at one end, and at a point three or four inches from the remaining end two angular extensions, 7t and it" These scveral arms or extensions are designed to be bent upward in the manner shown in Figs. 1 and 2, and thereby form a cheap and simple form of shoe.

Upon the central portion, h, of the shoe there is secured a stout metallic socket, G, which is designed to fit over the end of the shaft F. In this socket there is formed a slot, 9, which preferably narrows toward its inner end, and is indicated in Fig. 1. This slot is designed to receive a stud, g, which is placed upon and projects laterally from the shaft F. When the shoe is placed in position, the pressure of the foot against the same holds it securely in its position, and the tapering slot secures a firm connection between the shoe and the shaft, it being understood that the inner end of the slot is narrower than the width edges of the slot wear away the socket willbe allowed to slip farther on the shaft and to be bound in position by the pressure of the stud.

For the purpose of readily modifying the rate of revolution of the motor when it is driven by a constant current, a brake is employed, and this brake consists of a brakeshoe, K, resting upon one of the disks B, and supported from or pivoted to the tie-rod 70 of the motor. An arm, k extending from the shoe K, or from the pivoted support upon which it is carried, is provided with a weight, 70, which is adjustable toward and away from its axis of support. By moving the weight upon the arm it will be understood that the pressure of the brake may-be readily modified, and thus the rate of revolution of the machine.

The shoe or foot holder H, which has been described, may, it will be understood, be readily removed and various other devices may be substituted therefor, as required.

Attached to the central shaft, E, of the motor is a flexible shaft, N, which is designed to be employed for actuating any suitable form of rubbing devicesuch, for instance, as an oscillating rubber--which may, by reason of the flexibility of the shaft, be applied to the various parts or the body, without changing the position of the machine or of the patient.

I claim asemy invention 1. The combination, substantially as here inbefore set forth, with an electric motor and its central shaft, of a pitman, means, substantially such as described, for imparting a reciprocating movement to said pitman, a shaft coupled to said pitman, and receiving therefrom an oscillating movement, and a shoe or equivalent device carried upon said oscillating shaft.

2. The combination, substantially as hereinbeforeset forth, with an electric motor and its central revolving shaft, of a reciprocating pitman actuated by said shaft, an oscillating shaft actuated by said pitman, a foot moving device actuated by said oscillating shaft, and

an adjustable brake applied to said electric motor.

3. The combination, substantially as hereinbefore set forth, with a revolving electric motor and its shaft, of an oscillating shaft, a foot-receiving device actuated by said motor, and a flexible shaft attached to said motorshaft, substantially as described.

4. The combination, substantially as hereinbefore set forth, with an electric motor, its shaft, and means, substantially such as described, for modifying the rate of revolution of said motor, of an oscillating shaft actuated by said motor, a removable shoe applied to said oscillating shaft, which shoe is constructed with atapering slot, and a'stud projecting from said shaft, and adapted to enter said slot, which stud is of greater width than theinner end of said slot.

5. The combination, substantially as hereinbefore set forth, with an electric motor, a shaft, and means, substantially such as described, for imparting to said shaft an oscillating movement by the operation of said motor, of a removable shoe applied to said oscillating shaft, which shoe is constructed from a single piece of metal consisting of a central portion and four lateral projections, two of which are bent forward for embracing the heel, and two of which are bent upward for embracing the sides of the foot, substantially as described.

In testimony whereof I have hereunto subscribed my name, this 26th day of August, A. D. 1884.
